Hi again, As a few people pointed out, I misspoke in my earlier email.
When I calibrate C22 I immediately run CAL PLL and CAL FIL. True, the K2 does not directly reference C22 during normal operation. My calibration of C22 and then CAL PLL and CAL FIL is all by-the-book. That being said, I still do notice a temperature-dependent frequency drift during normal usage. The drift is predictable, with the zero beat on the dial I get with reference to WWV drifting by as much as 70-80 Hz if the temperature difference between ambient and the max temp the rig hits with the KPA100 under heavy use is large. The frequency at which I can zero-beat WWV does not change unpredictably. The radio consistently zero-beats low (e.g. WWV zero-beats at 10.000.07) when cold. Is this a really big deal? On SSB, certainly not. On CW I like to zero-beat dead-on with the narrow filters. Perhaps I'm just being a perfectionist.
